Application filed February 9, 1916. -Serial No. 77,228.

To all fwltom t may concern:

Be it known that I, GEORG FRANK, a"c1t1 zen of the United States, residing at Granger,

in the county of Yakima and State of Washington, have invented certain new and useful llmprovements in Reversible Envelope, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful* improvements in paper receptacles and more particularly to a reversible envelop and the primary object of the invention is to provide an envelop of this class which' may be readily reversed and 4used as a returnI envelop.

A further object of the invention resides in providing an envelop of improved and simple construction, inexpensive to manufacture and very useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim.

ln the accompanyingv drawing forming a part ofthiS application, Figure l is a plan v -view of the blank in its out-spread position.

`Fig. 2 is asimilar view thereofas it is initially folded and sealed.v Fig. 3 is a similar view showing the same folded and sealed in position for returning. Fig. 4 is a section as seen on line 4-4, of Fig. 2; and Fig. 5 is a similar view as seen on line 5 5, of Fig. 3. y

In describing my invention, lf shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which lindicates a blank or sheet of paper den signed to form my improved envelop, which consists of a central section 2q inclosed by the dotted lines, as indicated at 3 and formed on the one edge thereof, the bottom edge in the presentinstance, is a flap 4 which is substantially of the same size as the section 2. rthis flap 4 is designed to form the rear wall of the envelop, the same being bent with respect to the section 2, along the dotted line indicated therebetween and formed on the side edges of the central section 2, are the side aps 5, and formed on each of said side flaps, as'a continuation thereof, are the extensions or auxiliary side flaps 6. These extensions or auxiliary side Haps 6 are bendable with respect to the main side flaps 5, along the dotted lines indicated as 7 and the one face of each extension or auxiliary 'Hap 6 and the adjacent outer edges of the main side flaps 5, are gummed or covered with an adhesive of any preferred type, as clearly shown in Fig. l of the drawing.

Formed onthe edge of the central section 2, opposite that on which the flap 4 is formed, is a top or closing' flap 8 which is bendable withres'pect to the section 2 along the dotted lines therebetween and this flap is preferably of larger size than the side flaps 5 and designed for engagement with the outer face of the rear wall or bottom iap 4. Formed on, and designed to form a continuation of said flap 8, is the extension or auxiliary closing flap 9 which is bendable with respect to said fiap 8 along the dotted line indicated as l0. This auxiliary closing iiap 9 is the same with respect to the flap 8 as are the extensions or auxiliary iaps 6 with respect to the side flaps 5 `and the one faceiof said extension 9 and the adjacent face of the .flap 8 along the outer edges thereof isA gummed or covered with an adhesive, as clearly shown in Fig. 1.

In Fig. 1 of thc drawing, I have shown a plan view of the blank in its outspread position and disclosing the front face of the central section or front wall of the envelop prior to the formation thereof in its'original position and, in describingl the manner in which the envelop is folded, l will, for convenience, refer particularly to'this view. In the formation of the envelop. the rear wall or bottom flap 4 is first folded inwardly against the rear face of theI front wall or central section 2. The outer or auxiliary side flaps or 'extensions 6 are folded along the dotted lines 7, rearwardly against the rear or under faces of the side aps 6, whe1eupon said side flaps are then bent inwardly along the dotted lines between .the same and the central section 2, for contact .with the outer face of the rear wall of the bottom flap 4. Such disposition of the flaps will dispose the auxiliary flaps or extensions 6 inwardly with respect to the rear wall and the gummed faces thereof which are disposed inwardly, are moistenedand secured to the outer face of said rearwall 4. The envelop is then ready for use and the name and address of the addressee is then placed on the outer face of the front wall or section 2 of the envelop, as shown in Fig. l of the drawing. As this envelop is particularly adapted for use as a return envelop, the naine and address of the addresser is preferably provided on the under face of this central or front wall section 2 of the envelop prior to the folding thereof. This, I have shown somewhat in dotted lines in Fig. l of the drawing. Th letter or other communication may be placed in the envelop, as desired, and in sealing the saine, the extension or auxiliary closing flap 9 is bent inwardly against the under face of the closing flap S, along' the dotted line 10 and the complete closing `flap 8 bent inwardly along the dotted line between the same and the central section 2, against the outer face of the lower flap or rear wall 4.

kThis pcsitioiis the guniined face of the extension or auxiliary flap 9 against the outer face of the rear wall, and this gumnied face is moistened and properly engaged with the rear wall, thus completely sealing the envelop. l

In folding the auxiliary flaps of the side and closing iaps of the device'V in place and sealing the same, I provide preferably a flexible connection l1 which is disposed at the junctions ofthe auxiliary flaps and the main flaps, as indicated clearly in Fig. 2 of the drawing. The free ends of the flexible connection are permitted to project from the lower' edges of the side flaps, as clearly shown in Fig. 2 and when it is desired toy ppen the envelop, it is only necessary to draw upward-ly upon the ends of said connection, as shown in dotted lines in said Fig.

u`1, which operation .will sever the main side and closing flaps from the extension or auxiliary side and closing flaps. This will entirely open the envelop and permit the auxiliary flaps to be retained in secured positions against the outer face of the rear wall 4:. In using the same envelope for return purposes, it is only necessary then to bend this rear wall 5 backwardly over the opposite face of the front wall 2 and likewise bend the side flaps 5 backwardly against the outer face of the rear. wall 4 which, in this instance, is the opposite face, to the face which was previously considered the outer face of said rear wall. This will dispose the guniined edges of the Side flaps `inwardly and the saine may be moistened and secured to the rear Wall. The envelop is then ready for return use and after the return communication has been inserted therein, the closing flap 8 is then bent backwardly over the then outer face of the rear wall 4 and this also positions the guinined edges of the closing flap inwardly and the same may be moistened and properly sealed, thus completely sealing the envelop for return use.

From the foregoing it willbe seen that I have provided a simple, inexpensive and eii` cient means for carrying out the objects of the invention and while I have particularly described the elements best adapted to perthereto, side flaps formed on the side edges of said central section, also foldable in both directions with respect thereto, auxiliary side flaps forined on the outer edges of the lirst mentioned side flaps to form continuations of the latter, said auxiliary side aps being fold'alle inwardly with respect to the main side flaps, a closing flap formed on the upper edge of the central section and foldable in both directions with respect thereto, and an auxiliary closing flap formed on the outer edge of tlie first mentioned closing flap and foldable inwardly with respect thereto, the outer faces of said auxiliary side flaps and the adjacent faces of the main side flaps and the like faces of the closing flap and auxiliary flap being gummed.4 i A In testimony whereof I hereuntoaffix my signature in the. presence of two witnesses.
